The G41 powers 200 and 300 Series
installation loudspeakers in Remote
Active mode. It features active crossovers,
switched balanced and unbalanced
inputs, and employs the same low-
feedback topology as Meridian’s
G55/56/57 amplifiers, which was
developed from that used in the flagship
DSP8000K.
the speakers in use, and an appropriate
card is supplied with each loudspeaker.
Modules are available for the 320, 330
and 350, and each module includes a
pair of LEDs that confirm the positive
and negative power-rails are operative
and identifies the crossover installed by
means of the colour combination. 200
Series units can use the crossover or can
be driven in passive configuration with
the fourth amplifier pair configured for
two channels of full-range operation.
For years, Meridian loudspeakers have
been regarded as offering the highest
performance available – the result of
careful design, the highest-quality
drivers and components, transparent
crossovers and rigid, low-coloration
enclosures in both Active and Digital
Active designs.
The 300 Series consists of three ultra-
slimline systems for in-wall (surface
grille) and flush-mount (completely
hidden, eg behind wall coverings)
applications, featuring 6.5in (165mm)
metal-cone bass drivers, and a wide-
dispersion horn-loaded ribbon tweeter
for superb performance anywhere.
Remote Active units are supplied with
the appropriate crossover card for the
G41 Active Crossover unit.

Eight channels of approximately100W/8Ω
(180W/4Ω) RMS amplification are
provided, grouped into four pairs, each
providing bass and tweeter outputs from
a full-range input.
Now we have paid the same level of
attention to the design of loudpeakers
for installation purposes, including
in-wall, flush-mount and on-wall
configurations. These offer full Meridian
performance for systems where the use
of floor-standing models is impossible
or inappropriate.
Thermal, short-circuit and DC fault
protection circuitry is included. The G41
has soft start, fan output and trigger
input.
The 320 includes a single bass driver
and tweeter; the 330 adds an 8in
(200mm) Auxiliary Bass Radiator (ABR);
and the 350 features two bass drivers
and two ABRs.

The fourth channel pair can also be
configured as two full-range amplifiers
for driving a pair of passive loudspeakers,
eg for surrounds. To do this, the right-
hand modular crossover card is removed
and replaced by one providing additional
full-range unbalanced inputs.

A unique feature of the G41 is a cable-
length compensation switch. The
amplifiers have a negative impedance to
cancel out cable effects. This dramatically
improves performance, tightening the
bass response and giving significantly
improved control and punch. Two switch-
selectable settings are provided, one
for cables under 10m and the other for
cables over 10m in length. A separate
rear-panel switch is provided for each
pair of amplifiers.
The 200 Series in-ceiling/wall design
and the 300 Series of wall-mounting
systems allow exceptional flexibility of
configuration. This document describes
their application as remotely-driven
active in-wall/flush-mount speakers and
the G41 Powered Crossover/Amplifier
designed to power them; passive and
on-wall configurations are also available
and are detailed separately.
Heavy, rigid enclosures minimise wall
and cavity excitation so you hear the
speakers, and not wall resonances.

Replacement labels identify the
reconfigured output terminals (see rear
panel illustration below).
A white paintable low-resonance grille
and frame is included, and rough-in
boxes are available.
The crossover modules take the form of

of a stand-alone design in a discreet
enclosure with minimal visual impact
